All I need assistance on my 2010 Jeep Wrangler. The Jeep lost power while my wife was driving and I changed battery on side of road. Long story short, after 2 auto zone alternators I bought OEM from Jeep dealership plus a second pigtail. I still can get charge to battery. I’ve cleaned all grounds and connections. Checked fusable linkage. Tested everything and getting 12.2 V at alternator I put a load on and watch it drop something will not engage the alternator to charge battery and I am at loss. End up taking it to Christian brother automotive to run electrical diagnostics and was told it was the pig tail and alternator. So I installed the third OEM pig tail and alt. Same reaction. Any ideas will be greatly appreciated. Thank you.
 
Check the battery. There's a chance you ran it down so low that it can no longer hold a charge. You need to run a load test on it to see. That would be the very first place to start.
